POTATO-KILLER...

To all whom it may concern: i

a Be it known that I, HENRY HERMAN v companying drawings.

DI-Ns, a citizen of the United States,resid'- ing at Osceola,inithecounty of Fond du Lac and State of Wisconsin, have inventedcertain new and useful Improvements in Potato-Hillers, of which thefollowing is a specification, reference being had to the ac- Thisinvention relates to improvements in V p otato-hillers'; and an ,objectof this invention is to provide a potato hiller whichwill be simple inconstruction, comparatively cheap n manufacture and most efficlent anddurable in use.

Another object of this invention is toprovide a potato-hiller which willbe readily soil under cultivation.

In the drawings illustrating the principle of this invention and thebest mode now known-to me of applying that principle,

Figure 1 is a side elevation of my new potato-hiller; Fig. 2 is a planof the same; Fig. 3 is a section on the line A A of Fig.

of Fig. 1. I

The team-pole may be regarded as jointed or formed of two parts, thefront part a then constituting the tongue of the hiller, while the rearpart Z2 constitutes the center member or reach of thevehicle part of themachine. The rear part or perch b carries at its rear end abolster-block 0 in which is shaft, which serves as a rear axle d and onthe ends of which are mounted free to turn the rear wheels 6. Thevertical parts of the axle d are connected by the eyed brace-rods d withthe reach or perch b. To the front part of the latter is fastened across-bar f through'each end. of which passes rotatably '(or'in which isfulcrumed) a bent lever g having'on its lower end a rotatably-mounteddisk It. The upper end of each bent lever 'g is connected by a'linkz' tothe lowerrend of the crank arm 9' fastened to one end-of a shaft kjournaled in the pillow block 911- reach I).

When it is desired to force the disks h farther into the ground, thelever 79 is.

thrown to the front, as shown in dotted lines in Fig. '1, whereby therear end of the tongue or and the front end of the reach I) a arecarrled downwardly. At the same time the disks 7:. are forcedjinto thesoil. When it is desired to vary the angle at which the disks h are setto the longitudinal axis of the hiller, the lever 0 may be pulled to therear (or pushed to the front), whereby the bent levers g are turned inthe cross-bar f andthe disks h are carried into the desired position, asshown by the dotted lines in Fig. 2. The depths at which the disks areadjusted in the soil may be variedby the hereinbefore describedarrangement of parts without varying the burden or load thrown upon thenecks of the team-horses.

It is, obvious that the members .9, k may be regarded properly asrock-shaftsand,

that the-arms y, 0 act as rocker-arms on the rock-shaft'k.
